Inspect the mandate and holdings

ETFs trade on exchanges and may target equities, bonds, commodities or other markets. Similar names can hide different weights and replication methods. Check the mandate and holdings before judging diversification.

Compare results consistently

Management charges, spreads and dealing fees affect results. Implementation can also influence tracking. Match periods and dividend treatment instead of comparing a total-return series with a price-only series.

Distinguish shares from CFDs

Owning ETF shares differs from holding a CFD on their price. The latter can involve leverage and financing. Confirm the product type before assuming fund ownership or applying another instrument's terms.

Look for overlapping holdings

Two differently named equity ETFs may hold many of the same companies. Owning both does not necessarily create the expected diversification. Compare holdings and weights rather than the number of funds, using disclosures from matching dates to assess the actual overlap.
